Light metals 2021 P. 227-231Abstract: The work presents a study on alloys of the Al-Mg system (5–6 wt%) strengthened with Al3Er particles. The introduction of Al3Er particles into the Al-Mg melt was carried out using master alloys, a mechanical mixer. In addition, when casting into the chill mold, the melt was subjected to vibration treatment before solidification. The structure of the alloys obtained in the cast state of both initial (without particles) and containing particles was studied using metallography methods, i.e. optical and scanning electron microscopy. Analysis of the mechanical properties of the alloys under loading was carried out. It was revealed that the introduction of Al3Er particles does not affect the average grain size and hardness, but increases the ductility of the 1550 alloy.
